Description

Technical Field

[0001] This application relates to the field of computer technology, and in particular to a data processing method, apparatus, computer equipment, and medium for a blockchain network. Background Technology

[0002] Blockchain is a new application model of computer technologies such as distributed data storage, peer-to-peer transmission, consensus mechanisms, and encryption algorithms. Essentially, a blockchain is a decentralized database, a chain of data blocks linked together using cryptographic methods. Each data block contains information about a batch of network transactions, used to verify the validity of the information (anti-counterfeiting) and to generate the next block.

[0003] In existing applications, blockchain networks can serve multiple business systems. These systems can continuously poll the blockchain network to check for new blocks. If new blocks are generated, they can access or retrieve them. However, this frequent polling by multiple business systems puts immense pressure on the blockchain, leading to unstable service and high overhead. Summary of the Invention

[0017] The system will return an access failure message to the business system.

[0018] Optionally, the above-mentioned device is also used for:

[0019] Obtain the second access request sent by the business system before the second release time point; the second access request carries the data identifier of the business data to be accessed;

[0054] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0055] This application relates to blockchain-related technologies. Blockchain is a novel application model of computer technologies such as distributed data storage, peer-to-peer transmission, consensus mechanisms, and cryptographic algorithms. Essentially, a blockchain is a decentralized database, a chain of data blocks linked together using cryptographic methods. Each data block contains information about a batch of network transactions, used to verify the validity of the information (anti-counterfeiting) and generate the next block. A blockchain can include a blockchain underlying platform, a platform product service layer, and an application service layer. A blockchain consists of a series of blocks sequentially generated in chronological order. Once a new block is added to the blockchain, it cannot be removed. Each block records the data submitted by nodes in the blockchain system.

[0056] This application also relates to cloud technology. Cloud technology refers to a managed technology that unifies a series of resources such as hardware, software, and networks within a wide area network or local area network to realize the computing, storage, processing, and sharing of data.

[0057] Cloud technology is a general term encompassing network technology, information technology, integration technology, management platform technology, and application technology applied to cloud computing business models. It can form resource pools, providing flexible and convenient on-demand access. Cloud computing technology will become a crucial support. Backend services of technical network systems require substantial computing and storage resources, such as video websites, image websites, and many portal websites. With the rapid development and application of the internet industry, every item may have its own identification mark in the future, requiring transmission to backend systems for logical processing. Data at different levels will be processed separately, and various industry data will require robust system support, which can only be achieved through cloud computing. The cloud technology mentioned in this application refers to the data interaction between business systems and blockchain networks via the "cloud."

[0058] The relevant concepts involved in this application are described herein:

[0059] P2P network: A peer-to-peer network based on a specific network protocol. Instead of a central node to maintain the network state, each node maintains the overall network state or the connection state of its neighboring nodes through broadcast interactions with neighboring nodes.

[0060] SPV nodes: Lightweight nodes that do not save all transactions or download the entire block when verifying the existence of transactions; they only save the block header.

[0061] Optionally, SPV nodes can be used in the following scenarios: 1. Verifying payments in light wallets through SPV nodes; 2. In two-way pegging of sidechains, the main chain and the sidechain verify a specific transaction through SPV nodes to ensure that the transaction has indeed been paid, allowing one party to lock assets and the other party to transfer assets.

[0062] Please see Figure 1 , Figure 1 This is a schematic diagram of a network architecture for service processing provided in this application. For example... Figure 1 As shown, this network architecture can include a business network and a consensus network. The business network can include multiple business nodes, and the consensus network can include multiple consensus nodes. These two networks constitute a layered blockchain network, meaning they are not in the same network environment to protect the security of the consensus network. This network architecture can also include several business systems that can interact with the business nodes in the business network.

[0063] Both business nodes and consensus nodes can consist of one or more servers. These servers can be independent physical servers, server clusters or distributed systems composed of multiple physical servers, or cloud servers providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms. Terminal devices can be smart terminals such as smartphones, tablets, laptops, desktop computers, and smart TVs.

[0064] Please see also Figure 2 , Figure 2 This is a schematic diagram illustrating a data publishing scenario provided in this application. For example... Figure 2As shown, this example uses any one business node in the aforementioned business network. A business node can publish business data for the corresponding publication period to various business systems at each publication time point. For instance, a business node can publish business data for the first publication period (i.e., business data generated in the blockchain network during the first publication period) at the first publication time point, which could be the end time of the first publication period. Similarly, a business node can publish business data for the second publication period (i.e., business data generated in the blockchain network during the second publication period) at the second publication time point, which could be the end time of the second publication period. Likewise, a business node can publish business data for the third publication period (i.e., business data generated in the blockchain network during the third publication period) at the third publication time point, which could be the end time of the third publication period, and so on. The business data published by the business node can be business data that has been consensus-driven and uploaded to the blockchain by the consensus network.

[0065] Subsequently, each business system can access (e.g., pull or view) the business data published by the business system. For example, each business system can access the business data published by the business node within the first release period after the first release time point. Each business system can also access the business data published by the business node within the first and second release periods after the second release time point. Each business system can also access the business data published by the business node within the first, second, and third release periods after the third release time point.

[0066] As can be seen from the above process, by using the method provided in this application, each business system can periodically access the business data published by the business node at each publication time point. Before the next publication time point arrives, each business system does not need to constantly poll the business node to see if new data has been generated. By publishing data in this periodic rental form, the frequency of data access by the business system to the business node can be reduced, the stability of the business network can be improved, and the access overhead between the business system and the business network can be reduced.

[0067] Please see Figure 3 , Figure 3 This is a flowchart illustrating a data processing method for a blockchain network provided in this application. Figure 3 As shown, the method may include:

[0068] Step S101: When the first release time point for business data is reached, obtain the business data generated in the first release period corresponding to the first release time point in the blockchain network.

[0069] Optionally, the blockchain network may include a business network (also known as a witness network) and a consensus network (also known as a core network). The business network may include several business nodes. Optionally, the business network can be a p2p network (peer-to-peer network), and the business nodes in the business network can be lightweight nodes (such as SPV nodes) or other types of blockchain nodes. The number of business nodes in the business network can be determined based on the actual application scenario. The consensus network may include several consensus nodes. These consensus nodes are mainly used to reach consensus on the business data submitted in the blockchain network (such as transaction data from a business system). The business data held by the business nodes in the business network can be the business data provided by the consensus network after consensus has been passed. The consensus network can also be a p2p network, and the number of consensus nodes in the consensus network can be determined based on the actual application scenario.

[0070] In this application, both business nodes and consensus nodes are blockchain nodes within the blockchain network. Each blockchain node can consist of one or more computer devices, which can be terminal devices or servers. Therefore, it can be understood that the executing entity in this application can be any business node in the business network, meaning that all business nodes operate on the same principle. The executing entity in this application will be collectively referred to as a business node below.

[0071] Business systems can communicate with business nodes to access (e.g., pull or view) business data generated in the blockchain network (this generated business data can refer to the business data provided to business nodes after consensus is reached by the consensus network). For example, a business node can be a lightweight node, and the business data accessed by the business system can be invoice data. Here, "business system" can refer to a client system, which can reside on a user's device (e.g., a user's terminal device). The blockchain network can be understood as a backend network that provides business services to the business system.

[0072] There may be one or more business systems, and the specific number of business systems is determined based on the actual application scenario and is not limited thereto. In this application, the data interaction between a business node and a business system (such as access after data publication) is used as an example for illustration. It can be understood that the data interaction principle between a business node and any business system is the same and independent.

[0073] Business nodes can periodically publish business data generated in the blockchain network, enabling business systems to access the periodically published business data. For details, please refer to the following description.

[0074] When the first release time for business data is reached, the business node can obtain the business data generated in the first release period corresponding to the first release time in the blockchain network. The first release time can refer to any time point when business data needs to be released (which can be called the release time point or period time point), and the first release period corresponding to the first release time point can refer to the release period to which the business data released at the first release time point belongs.

[0075] For example, if business data needs to be published every hour (i.e., the cycle length is 1 hour), and the initialization starts from 1 o'clock, that is, the timer starts from 1 o'clock, then 2 o'clock can be used as the first publication time point. The first publication cycle corresponding to the first publication time point (i.e., 2 o'clock) can refer to the cycle from 1 o'clock to 2 o'clock (which can be called the publication cycle). The business data generated within the first publication cycle can refer to the business data generated within the blockchain network from 1 o'clock to 2 o'clock.

[0076] Therefore, the next release time point could be 3 o'clock, the next release time point could be 4 o'clock, and so on. The business processing logic is the same at each release time point. Therefore, this application uses the business processing logic at the first release time point as an example for explanation. The first release time point can be any release time point.

[0077] Therefore, upon reaching the aforementioned first release time point, the business node can obtain the business data generated within the first release cycle corresponding to the first release time point.

[0078] Specifically, business nodes can obtain business data generated within the first release period corresponding to the first release time point through the block height. For example, if the highest block height in the blockchain network at the previous release time point is h1 and the highest block height in the blockchain network at the first release time point is h2, then the business node can obtain block data (which includes business data) with block heights between h1 and h2 for release.

[0079] Optionally, before a business node begins publishing business data (such as before the first publishing time point mentioned above), the process by which the business node determines the publishing time and period for the business data can be as follows:

[0080] Business nodes can obtain data publishing contracts (a type of smart contract, which can be loaded onto business nodes by administrators through a management platform) for business data of at least one data type. The specific number and types of business data types can be determined based on the actual application scenario and are not limited thereto.

[0081] The data publishing contract is configured with publishing logic for each type of business data among the above-mentioned at least one type of business data. The publishing logic may include the publishing time point and publishing cycle of the business data.

[0082] Therefore, business nodes can determine the corresponding publication time points for each type of business data based on the aforementioned data publication contract. The publication time points and publication cycles (collectively referred to as publication logic) for different data types can be the same or different, depending on the actual application scenario. It is understandable that the principle for publishing business data of each data type is the same and independent of each other. In other words, business nodes can generate the publication time points (i.e., the nodes of the publication cycle) for various data types of business data locally based on the data publication contract.

[0083] Therefore, the business data acquired by the aforementioned business nodes within the first release period corresponding to the first release time point can be business data of any data type. This application uses the release process of business data of any data type as an example for illustration.

[0084] Furthermore, it is understandable that there may be multiple types of business data with the same release time (such as the first release time) and release period (such as the first release period). Therefore, the business data obtained by the above-mentioned business nodes within the first release period corresponding to the first release time may include business data of multiple data types. These multiple types of business data may be obtained separately and released separately in the future.

[0085] Alternatively, the next publication time point after the first publication time point can be referred to as the second publication time point. If the pending business data needs to be reviewed after reaching the first publication time point but before reaching the second publication time point, the next publication time for the pending business data (such as the second publication time point) can be postponed. For example, the second publication time point can be postponed to a target publication time point, which can be any time point after the second publication time point. This target publication time point can be determined according to the actual application scenario and is not restricted. The pending business data can include business data generated in the blockchain network between the first and second publication time points.

[0086] For example, if the second release time is 3 o'clock, the second release time can be delayed by half an hour so that the target release time can be 3:30.

[0087] By postponing the second release date, it is easier to review the pending business data. Therefore, after postponing the second release date, the pending business data can be reviewed, such as whether the pending business data is legal and complete.

[0088] Therefore, once the pending business data has passed review (e.g., the data is deemed valid / complete) and the target release time has arrived, the business node can release the approved pending business data to the business system. The second release time can be postponed to the target release time by adjusting the parameters in the data release contract.

[0089] Optionally, if the pending business data fails the review, the pending business data can be left unpublished. Instead, the pending business data can be corrected, and after the correction is completed, the pending business data can be put on the blockchain and subsequently published again.

[0090] Therefore, the method provided in this application can also meet the business scenarios of reviewing business data, making the review process of business data easier and more convenient.

[0091] Please see Figure 4 , Figure 4 This is a schematic diagram illustrating a data acquisition scenario provided in this application. Assuming a release cycle lasts one hour, and the data release process is initialized starting at 1:00, then 2:00 can be considered a release time point. The release cycle corresponding to 2:00 is release cycle 1. If 2:00 is taken as the first release time point, and release cycle 1 (i.e., 1:00 to 2:00) is taken as the first release cycle, and the highest block height in the blockchain network is 100 at 1:00 and 200 at 2:00, then the business node can obtain the business data generated within release cycle 1 (i.e., the business data contained in blocks with block heights of 100 to 200).

[0092] Next, 3:00 can also be used as a release time point. The release period corresponding to 3:00 is release period 2. If 3:00 is taken as the first release time point, and release period 2 (i.e., 2:00 to 3:00) is taken as the first release period, and the highest block height in the blockchain network at 3:00 is 300, then the business nodes can obtain the business data generated within release period 2 (i.e., the business data contained in the block data with block heights of 200 to 300). And so on.

[0093] Optionally, the block data may include transaction data from the business system, and the business data included in the block data may refer to the invoice data of the business system in the transaction data.

[0094] Step S102: Publish the business data generated within the first publication period to the business system, so that the business system can access the business data generated within the first publication period after the first publication time point.

[0095] Optionally, business nodes can publish the business data generated within the first publication period to the business system, enabling the business system to access (pull) the published business data generated within the first publication period after the first publication time point. For example, the business data could be invoice data from the business system; the business system can pull its own invoice data and perform subsequent business processing on it, such as reviewing business transactions using the invoice data.

[0096] After the business node publishes the business data generated within the first publication cycle to the business system, it can generate a first publication success message. This first publication success message includes the first publication cycle and the second publication time point, which refers to the next publication time point after the first publication time point.

[0097] The business node can return the first successful publication notification message to the business system. This first successful publication notification message can serve as a data publication credential. It may also include a combination of nonce (an arbitrary or non-repeating random value used only once) and the business node's HMAC value (message authentication code). This nonce combination and the business node's HMAC value prove that the first successful publication notification message was published by the business node; they can be understood as the business node's identity verification information.

[0098] The first release success notification message indicates that the business system can access business data generated within the first release period before the second release time point. This message also indicates that the business system can access business data generated in the blockchain network between the first and second release time points upon reaching the second release time point. This eliminates the need for the business system to poll the blockchain network for new business data generated after the first release time point and before the second release time point, reducing the frequency of blockchain network access, preventing resource consumption from high-frequency polling, and improving the overall system service availability.

[0099] Furthermore, as described above, business systems typically can access business data published by business nodes, but cannot access unpublished business data. Therefore, in this application, when certain business systems require immediate access to business data, they can request to register a real-time access credential with the business node (registration can be done through the aforementioned data publishing contract). This credential can then be used to access the latest business data generated in the blockchain network. This process may include:

[0100] The business system can send a real-time access request to the business node, and the business node can obtain the real-time access request sent by the business system. This real-time access request is used to request real-time access to business data in the blockchain network.

[0101] Therefore, the business node can verify the system identity of the business system that submitted the real-time access request through the real-time access request. If the verification is successful, a real-time access credential for the business system can be generated. This real-time access credential can be generated using the private key of the business system, and the business node can return the real-time access credential to the business system.

[0102] Subsequently, the business system can access the business data generated within a target time interval in the blockchain network using the real-time access credential after reaching the first release time point and before reaching the second release time point. This target time interval can refer to the time interval formed by the first and second release time points. In other words, the business system can access the latest real-time generated business data in the blockchain network using the real-time access credential it holds.

[0103] Please see Figure 5 , Figure 5 This is a schematic diagram illustrating a data access scenario provided in this application. For example... Figure 5 As shown, ① a business system can request to register for real-time access services from business nodes in the business network, such as by sending a real-time access request to a business node; ② after receiving the registration request, a business node can verify the identity of the business system that sent the request. If the identity verification of the business system is successful, the business node can generate a real-time access credential for the business system using the business system's private key, and then return the real-time access credential to the business system.

[0104] Furthermore, ③ the business system can request access to real-time data (such as business data generated in real time but not yet published in the blockchain network) by using the real-time access credentials it holds; ④ the business nodes in the business network can then return the real-time data they accessed to the business system.

[0105] If the business system has not registered the aforementioned real-time access credentials, and before the second publication time point, receives an access request (referred to as the first access request) from the business system for accessing business data generated within the target time interval, the business node can generate an access failure message based on the first access request and return the generated access failure message to the business system. This access failure message can be used to indicate to the business system that the business data within the target time interval has not yet been published and cannot be accessed.

[0106] Furthermore, business nodes can also obtain a second access request sent by the business system before the second publication time point. This second access request carries a data identifier of the business data that the business system needs to access. The business data indicated by this data identifier (i.e., the business data that the business system wants to access) can be referred to as the target business data. If the target business data is business data generated in the blockchain network before the first publication time point, the business node can obtain the target business data and return the obtained business data to the business system. This process indicates that the business system can successfully access any business data published before the latest publication time point (such as the first publication time point).

[0107] Please see Figure 6 , Figure 6 This is a schematic diagram illustrating a data access scenario provided in this application. For example... Figure 6 As shown, publication time point 2 can be the first publication time point mentioned above, and publication time point 3 can be the second publication time point mentioned above. If the current time is between publication time point 2 and publication time point 3, that is, the current time exceeds publication time point 2 but has not yet reached publication time point 3, then non-real-time access business systems (i.e., business systems that have not registered real-time access credentials) can access business data published by business nodes before publication time point 2, while real-time access business systems (i.e., business systems that have registered real-time access credentials) can access any business data generated before the current time.

[0108] Furthermore, the next release time after the first release time is the second release time. Therefore, when the second release time is reached, the business nodes can also obtain the business data generated in the second release cycle corresponding to the second release time in the blockchain network.

[0109] Business nodes can also publish business data generated during the second release cycle to the business system, so that the business system can access the business data generated during the first release cycle and the business data generated during the second release cycle after the second release time point.

[0110] Similarly, after a business node publishes the business data generated during the second publication cycle to the business system, it can generate a second publication success message. This message includes the second publication cycle and the third publication time point, which refers to the next publication time point after the second publication time point.

[0111] The business node can return the second successful publication notification message to the business system. This second successful publication notification message can also serve as a data publication credential. The first successful publication notification message can also include a combination of nonce (an arbitrary or non-repeating random value used only once) and the business node's HMAC value (message authentication code). This nonce combination and the business node's HMAC value are used to prove that the second successful publication notification message was published by the business node; they can be understood as the business node's identity verification information.

[0112] The second release success notification message indicates that the business system can access business data generated within the second release period before the third release time point. This message also indicates that the business system can access business data generated in the blockchain network between the second and third release time points upon reaching the third release time point. This eliminates the need for the business system to poll the blockchain network for new business data generated between the second and third release time points, thus reducing the frequency of blockchain network access.

[0113] Please see Figure 7 , Figure 7 This is a schematic diagram of a data processing scenario provided in this application. For example... Figure 7 As shown, each consensus node can reach a consensus on the business data submitted in the blockchain network, and then provide the business data that has passed consensus to the various business nodes for on-chain processing. Each business node contains a business publishing contract (i.e., the aforementioned data publishing contract), through which the publishing logic (such as publishing time and publishing cycle) corresponding to various types of business data can be determined. Therefore, business nodes can periodically publish business data to the business system according to the publishing logic corresponding to each type of business data, enabling the business system to access the business data published by the business nodes.

[0114] Please see Figure 8 , Figure 8 This is a schematic diagram illustrating a data interaction scenario provided in this application. For example... Figure 8As shown, a routing proxy network can separate the business network from the core network (i.e., the consensus network), and the network environments of the business network, core network, and routing proxy network can be isolated from each other. The business network contains several business nodes, the core network contains several core nodes (i.e., consensus nodes), and the routing proxy network contains several proxy nodes.

[0115] The business network can interface with the front-end business systems to exchange data and execute corresponding business operations (such as a business system requesting access to business data from a business node). The core network, on the other hand, performs consensus on data that needs to be uploaded to the blockchain. To ensure the security of the core network, it typically does not directly interface with the front-end business systems. The business network and the core network can communicate and interact through proxy nodes in a routing proxy network, which further enhances the security of the core network.

[0116] When the first publication time point for business data is reached, this application can obtain the business data generated within the first publication period corresponding to the first publication time point in the blockchain network; and can publish the business data generated within the first publication period to the business system, enabling the business system to access the business data generated within the first publication period after the first publication time point. Therefore, this application can periodically publish business data to the business system, allowing the business system to access the published business data after the publication time point without constantly polling the business data generated in the blockchain network. This improves the business stability of the blockchain network and reduces the overhead of accessing business data within the blockchain network.
